The Wall Street Journal and Bloomberg have also similarly insisted at least one model of Apple's next premium iPhone will have a trio of lenses on its rear.

A recent research note from analyst Ming-Chi Kuo, from TF International Securities, declared Apple is planning to upgrade all three models of its current iPhone lineup.

That means in addition to the iPhone Xs and Xs Max, the iPhone XR could also see an update.

Most notably, Kuo suggested the successors to the iPhone Xs and Xs Max will come with three cameras on their rear while the next version of the XR could only come with two.

Plus, he was eager to state the added lens for the presumably titled iPhone 11 and 11 Max would offer an ultra wide-angle.

Such a feature has already been seen in Android rivals such as the Samsung Galaxy S10 and Huawei P30 Pro.

While Apple's next batch of premium iPhones have been rumoured to present fans with a substantial camera upgrade, it is possible the product could also tout a major new feature that could beat its Android rivals.

Patently Apple recently discovered a patent granted to Apple that suggests the firm is experimenting with a new way to unlock its iPhones.

The document discussed the implementation of a Touch ID system that harnesses an "acoustic imaging system" housed under the phone's display to deliver a futuristic method of unlocking.

Essentially, the patent describes the technology that would send out mechanical waves, acoustic waves and pulses in order scan a user's finger and open the hardware in question.

The system was noted to work wherever the user placed their finger on the display which would present a sizeable upgrade over current ultrasonic and optical readers available on competing smartphones.

Express.co.uk has tested devices such as the OnePlus 6T, Huawei P30 Pro, Samsung Galaxy S10 and has noted the small area in which the scanner covers means there are times when user fingers miss the region entirely.

Such a problem would be alleviated if the entire display of a smartphone functioned as a sensor.

Patently Apple insisted the patent also said the acoustic method could be used to scan user ears if they were placed on the device.

While the document describes futuristic technology that could present Apple's iPhone with a huge advantage over its rivals, it is worth noting the existence of the patent does not mean it is an expected feature for the new iPhone 11.

That is because technology companies file numerous patents during the course of product development, not all of which debut in final releases.
